When General Sherman was in Louisville in October, IStiJ, ho was called upon by Secretary Cameron, and they engaged in a general discussion of the military situation. General Sherman said that for aggressive movements, tho United States would require 200,000 men. This was so far beyond the ideas of the time that he was regarded as crazy, and was soon after relieved from his command by General Buell. Secretary Cameron was blamed for this, but his letter to me, here inserted, shows that he was absent from Washington when the order was made:

WAR Hi-:]-AIIT.MKNT, November 14, 1801.

Snt: — Your letter of tlio lOtli inst. is received. GiMioral Shonnan was reunited from tho comnmwl in Kontuoky during my absence at tho north on official business.
